Foot: From 2 Different Sources
The foot has 2 vital functions: to support the weight of the body in standing or walking and to act as a lever to propel the body forwards.
The largest bone of the foot, the heelbone (see calcaneus), is jointed with the ankle bone (the talus). In front of the talus and calcaneus are the tarsal bones, which are jointed the 5 metatarsals. The phalanges are the bones of the toes; the big toe has 2 phalanges; all the other toes have 3.
Tendons passing around the ankle connect the muscles that act on the foot bones. The main blood vessels and nerves pass in front of and behind the inside of the ankle to supply the foot. The undersurface of the normal foot forms an arch supported by ligaments and muscles. Fascia (fibrous tissue) and fat form the sole of the foot, which is covered by a layer of tough skin.
Injuries to the foot commonly result in fracture of the metatarsals and phalanges. Congenital foot abnormalities are fairly common and include club-foot (see talipes), and claw-foot. A bunion is a common deformity in which a thickened bursa (fluid-filled pad) lies over the joint at the base of the big toe. Corns are small areas of thickened skin and are usually a result of tight-fitting shoes. Verrucas (see plantar warts) develop on the soles of the feet. Athlete’s foot is a fungal infection that mainly affects the skin in between the toes. Gout often affects the joint at the base of the big toe. An ingrowing toenail (see toenail, ingrowing) commonly occurs on the big toe and may result in inflammation and infection of the surrounding tissues (see paronychia). Foot-drop is the inability to raise the foot properly when walking and is the result of a nerve problem.
n. the terminal organ of the lower limb. From a surgical point of view, the human foot comprises the seven bones of the *tarsus, the five metatarsal bones, and the phalangeal bones plus the surrounding tissues; anatomically, the bones and tissues of the ankle are excluded.
Claw-foot, or PES CAVUS, is a familial deformity of the foot characterised by an abnormally high arch of the foot accompanied by shortening of the foot, clawing of the toes, and inversion, or turning inwards, of the foot and heel. Its main e?ect is to impair the resilience of the foot resulting in a sti? gait and aching pain. Milder cases are treated with special shoes ?tted with a sponge rubber insole. More severe cases may require surgical treatment.... claw-foot
See TALIPES.... club-foot
The term applied to a condition which develops as a result of prolonged immersion of the feet in cold or cool water. It was a condition commonly seen during World War II in shipwrecked sailors and airmen who had crashed into the sea, spending long periods there before being rescued. Such prolonged exposure results in VASOCONSTRICTION of the smaller arteries in the feet, leading to coldness and blueness and ?nally, in severe cases, to ulceration and GANGRENE.

A condition in which the foot cannot be raised properly and hangs limp from the ankle. Neuritis affecting the nerves that supply muscles that move the foot is a common cause and may be due to diabetes mellitus, multiple sclerosis, or a neuropathy. Weakness in the foot muscles can also result from pressure on a nerve (due to a disc prolapse or a tumour) as it leaves the spinal cord. Treatment is of the underlying cause, but in many people the weakness persists. A lightweight plastic caliper splint can be used to keep the foot in place when walking.... foot-drop
